PTD Staff Clarifies Fencing Cost Method and Adjustments

In the May/June 1999 issue of STATEMENT, the Comptroller's Property Tax Division (PTD) staff found two errors in the article on the method of estimating fence costs using the Marshall & Swift Valuation Guide. PTD apologizes for the omission and for any confusion that the errors may have caused.

The article did not include the "Unit-in-Place Multiplier" calculation. This multiplier is found in Section 99, Page 3, of the Guide. The multiplier updates the base costs, after deductions, to a current cost basis for the United States Central Region as of January, 1997.

In the article, the local multiplier was incorrectly applied to the base costs. The local multiplier should be applied to the base costs after deductions.

The example provided in the May/June issue is shown below, using the corrected method for estimating fence costs.
